A unit that defines a signal level by comparing it to a reference level. The reference level of 0dBm is defined as 1mW. The signal level in dBm is 10 times the log of the signal's power over that of the 0dBm reference.

   don't bother me

Abbreviation. dB referenced to one milliwatt. Note 1: dBm is used in communication work as a measure of absolute power values. Zero dBm equals one milliwatt. Note 2: In DOD practice, unweighted measurement is normally understood, applicable to a certain bandwidth, which must be stated or implied. Note 3: In European practice, psophometric weighting [..]

A unit used to express power level in decibels

dB power relative to a 1 milliwatt standard.

 - Decibels compared to one milliwatt. The higher the dBm, the higher the devices transmit or receive power.

Stands for "Data Base Management" routines, a set of routines that emulate an associative array using disk files. The routines use a dynamic hashing scheme to locate any entry with only two disk accesses. DBM files allow a Perl program to keep a persistent hash across multiple invocations. You can tie your hash variables to various DBM im [..]

Stands for “Database Management” routines, a set of routines that emulate an associative array

A logarithmic expression for power, referenced to 1 milliwatt. dBm = 10 log (power / 1 mW). See decibel.

This is decibels with respect to 1 mW of power.  +30 dBm = 0 dBW.

An abbreviation used to represent power levels above or below a 1-milliwatt reference.

The power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW).
